The brain is a bilateral, soft, symmetrical, gelatinous structural unit. Surrounded by a meningeal that is covered by its head and extends continuously into the spinal cord. At birth, the brain weighs less than 400 g. The adult human brain weighs from 1250 to 1450 g and differentiates according to sex. The central nervous system (CNS) is composed of the brain and spinal cord. The peripheral nervous system (PNS) is composed of spinal nerves that branch from the spinal cord and cranial nerves that branch from the brain. Men's brains weigh 2 times more than women. (1) The brain is the organ that is the center of control of the body, in short it controls everything we do: thinking, dreaming, sports, sleep. The brain can be divided into too many parts where different parts are connected to each other specifically. Each part has its own work to be done, which makes the brain multifunctional. By working in tandem with the nervous system, the brain sends and receives messages and establishes connections with the outside world.
